Perhaps this is an issue with ARM - and such diffs are expected - as we already have multiple alt files for some of these tests

This one is puzzling - missing fortran stdout? Perhaps compile issue on ARM? [its a sequential example - so can't blame MPI]

Or they are all related to the optimization flags used? What configure options were used for the build?

The differences could possibly be related to the use of real() and maybe the direct use of floating point numbers that the compiler first treats as single and then converts to double thus losing precision.

And I get the error code 1 in different tests on different machines.I don’t know what is error code1. What case this? How can I fix the failure tests.
